Application filed March 1, 1916. Serial No. 31,358.

To all whom it may concern Be it known that I, MAGNUS BOODE, a subject of the King of Great Britain, residing at Lacombe, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Feed-Grinding Machines, of which the following is a specification.

My invention relates to improvements'in feed grinding machines.

The objects of the present invention are to provide a machine of the character described in which the grinding may be effected with the minimum motive power, and with more advantageous results.

To the accomplishment of the recited ob jects, and others coordinate therewith, the preferred embodiment of my invention resides in that arrangement of parts shown in the accompanying drawings, hereinafter described, and embraced within the scope of the appended claim.

In said drawings- Figure 1 is a vertical elevation of the machine embodying my invention.

Fig. 2 is a vertical sectional view taken along lines 22 of Fig. 1, and

Fig. 3 is a transverse section taken along line 3-3 of Fig. 1.

Referring more particularly to the drawings for a detail description of my invention, a designates the hopper having a throat 6 adapted to be closed by the slide valve c. The hopper and its appurtenances are sustained by pairs of supports 6 e which in turn are secured to the table or stand y. Below the throat b and between the supports 6 e is a balanced chute d pivoted to the side plates 7 at 7, and beneath the chute is the main roller 71 having its shaft h trunnioned in the bearings it upon opposite sides of the table y. Adjacent the discharge end of the chute d is pivoted as at m to the bracket n, a shoe 8 provided with a concave guide face r and a reinforcing rib r, the lower extremity of the shoe being curved to conform to the contour of the roller 2'. A rod p is extended through a bracket 39 and opien at this patent an be obtained; for

screws into the base of the shoe and has a coil spring, 0, between the shoe and theadjacent wall of the bracket p. The

In operation, the grain is fed into the re ceiving hopper a, through throat b, and falls in the pivoted and balanced hopper cl, from whence it passes into the concavity r and down between the roller '21 and shoe 8. The yieldable feature of the shoe allows for the passage of any foreign body that may accidentally fall between the grinding surfaces, and the required pressure may be secured by an appropriate adjustment of the rod 3). An auxiliary adjustment may be obtained by moving the bracket n upon the screw 0.

It should be understood that in broader aspects my invention comprehends the employment not only of the various means described, but of similar means for performing the recited functions. It is desired to reserve the right to efiect such changes and modifications as may be deemed to come fairly within the scope of the appended claim.

What I claim is In a feed grinding machine, the combination of a support having an opening therein, with a grinding roller journaled on said support within said opening, a feed hopper on said support above said roller, a swinging chute arranged below said hopper and adapted to discharge onto said roller, a bracket secured on said support, a concave shoe pivotally connected at its upper end to the hopper end of said bracket, said shoe supporting said chute, and means for adjusting the lower end of said shoe relative to said grinding roller.

In testimony whereof I afiix my signature in the presence of two witnesses.

GNUS BOODE.
